Das Befestigungselement ermöglicht, durch einfaches Einsetzen und Befestigen der Hülse im ersten Bauteil und Einschrauben des Verbindungselements im zweiten Bauteil eine (kraftschlüssige und/oder formschlüssige) Verbindung zwischen zwei Bauteilen, beispielsweise einer Karosserie und einem Anbauteil herzustellen. Das Befestigungselement lässt sich nach der erfolgten Montage durch Verdrehen des Verbindungselements in axialer Richtung einstellen und durch späteres Herausziehen des Verbindungselements aus dem Clip wieder trennen. Dabei bleibt die eingestellte Position für ein erneutes Befestigen bestehen.The fastening element makes it possible to produce a (non-positive and/or positive) connection between two components, for example a body and an attachment, by simply inserting and fastening the sleeve in the first component and screwing in the connecting element in the second component. After assembly, the fastening element can be adjusted by rotating the connecting element in the axial direction and separated again by later pulling the connecting element out of the clip. The set position remains for re-fastening.

Das erste Bauteil kann beispielsweise ein Trägerbauteil sein, insbesondere ein Karosserieblech eines Fahrzeugs.The first component can be a carrier component, for example, in particular a body panel of a vehicle.

Das zweite Bauteil kann zum Beispiel ein Anbauteil, wie eine Heckleuchte oder eine Seitenleuchte, sein.The second component can, for example, be an add-on part such as a rear light or a side light.

In einer Ausführungsform weist der zweite Befestigungsbereich einen Gewindeabschnitt zum Eingreifen in einer Aufnahme des zweiten Bauteils auf. Der Gewindeabschnitt kann als ein selbstfurchendes oder metrisches Gewinde, insbesondere selbsthemmend, ausgebildet sein, welches in einer Aufnahme des zweiten Bauteils form- und/oder kraftschlüssig eingreift, welches sich insbesondere in die Aufnahme einschraubt. In einer weiteren Ausführungsform kann der zweite Befestigungsbereich in dem zweiten Bauteil festgelegt, insbesondere eingepresst, eingeklebt, eingespritzt oder eingeclipst oder einstückig mit dem zweiten Bauteil ausgebildet sein.In one embodiment, the second fastening area has a threaded section for engaging in a receptacle of the second component. The threaded section can be designed as a self-tapping or metric thread, in particular self-locking, which positively and/or non-positively engages in a receptacle of the second component, which in particular is screwed into the receptacle. In a further embodiment, the second fastening area can be fixed in the second component, in particular pressed in, glued in, injected or clipped in, or formed in one piece with the second component.

In einer Ausführungsform ist die Antriebsschnittstelle als eine untere Antriebsschnittstelle ausgebildet, die vom in das Ausgleichselement eingesetzten Verbindungselement weg weist und/oder die Antriebsschnittstelle ist als eine obere Antriebsschnittstelle ausgebildet, die zu dem in das Ausgleichselement eingesetzten Verbindungselement hin weist. Auf diese Weise kann das Ausgleichselement verstellt werden, wenn die Hülse im ersten Bauteil befestigt ist und das Verbindungselement im zweiten Bauteil verschraubt ist.In one embodiment, the drive interface is designed as a lower drive interface that is inserted into the compensating element Connection element points away and/or the drive interface is designed as an upper drive interface, which points towards the connection element inserted into the compensating element. In this way, the compensating element can be adjusted when the sleeve is fastened in the first component and the connecting element is screwed into the second component.

In einer Ausführungsform umfasst die Antriebsschnittstelle einen Außen- oder Innensechskant oder -vierkant, einen Außen- oder Innensechsrund, einen Schlitz oder einen Kreuzschlitz. Andere Formen der Antriebsschnittstelle sind ebenfalls möglich.In one embodiment, the drive interface comprises an external or internal hexagon or square, an external or internal hexalobe, a slot or a cross slot. Other forms of drive interface are also possible.

In einer Ausführungsform weisen das Ausgleichselement und die Hülse zueinander komplementäre Gewinde auf. Auf diese Weise kann die Verstellung in Längsrichtung durch Verdrehen erfolgen.In one embodiment, the compensating element and the sleeve have mutually complementary threads. In this way, the adjustment can be made in the longitudinal direction by twisting.

In einer Ausführungsform ist das Verbindungselement in der Aufnahme lösbar, aber gegen Herausziehen gehemmt gehalten. Auf diese Weise kann das zweite Bauteil vom ersten Bauteil abgezogen und wieder aufgesteckt werden. Der zuvor durch Verdrehen des Verbindungselements im zweiten Bauteil eingestellte axiale Abstand bleibt dabei erhalten.In one embodiment, the connecting element is detachable in the receptacle, but is held in a manner that prevents it from being pulled out. In this way, the second component can be removed from the first component and reattached. The axial distance previously adjusted by twisting the connecting element in the second component is retained.

In einer Ausführungsform ist das Ausgleichselement im Bereich der Aufnahme elastisch ausgebildet.In one embodiment, the compensating element is designed to be elastic in the area of the receptacle.

In einer Ausführungsform ist zur Abtrennung des ersten Befestigungsbereiches vom zweiten Befestigungsbereich ein Trennflansch am Verbindungselement vorgesehen.In one embodiment, a separating flange is provided on the connecting element to separate the first fastening area from the second fastening area.

In einer Ausführungsform ist eine Mutter zum Aufschrauben auf die Hülse vorgesehen, um das Befestigungselement am ersten Bauteil mittels einer Schraubverbindung zu halten. Alternativ sind auch Clipverbindungen möglich.In one embodiment, a nut is provided for screwing onto the sleeve in order to hold the fastening element on the first component by means of a screw connection. Alternatively, clip connections are also possible.

In einer Ausführungsform weisen die Mutter und die Hülse eine zueinander komplementäre Verzahnung auf, die konfiguriert ist, das Lösen oder Verlieren der Mutter zu erschweren.In one embodiment, the nut and sleeve have complementary serrations configured to make the nut more difficult to loosen or lose.

In einer Ausführungsform ist in der Aufnahme ein Federelement zur formschlüssigen und/oder reibschlüssigen Verbindung des Ausgleichselements am Verbindungselement angeordnet. Ein solches, axial in beide Richtungen innerhalb der Aufnahme fixiertes Federelement kann Kräfte, wie eine Einführkraft und eine Ausziehkraft, insbesondere Druck- bzw. Zugkräfte, axial in beide Richtungen übertragen und in Richtung der Aufnahme ableiten, so dass das Befestigungselement mehrmals genutzt werden kann.In one embodiment, a spring element is arranged in the receptacle for the positive and/or frictional connection of the compensating element to the connecting element. Such a spring element, which is fixed axially in both directions within the receptacle, can transmit forces such as an insertion force and an extraction force, in particular compressive or tensile forces, axially in both directions and dissipate them in the direction of the receptacle, so that the fastening element can be used several times.

In einer Ausführungsform weist die Hülse eine Schnittstelle zur Aufnahme in der Aufnahmeöffnung des ersten Bauteils auf, wobei die Schnittstelle einen von der Kreisform abweichenden Querschnitt aufweist und/oder wobei die Schnittstelle einen kleineren Querschnitt als die Aufnahmeöffnung aufweist. Somit wird ein Verdrehen der Hülse in der Aufnahmeöffnung erschwert und/oder eine Positionseinstellung quer zur Längsrichtung ermöglicht.In one embodiment, the sleeve has an interface for receiving in the receiving opening of the first component, the interface having a cross section that deviates from the circular shape and/or the interface having a smaller cross section than the receiving opening. This makes it more difficult for the sleeve to rotate in the receiving opening and/or allows the position to be adjusted transversely to the longitudinal direction.

Figur 5 ist eine schematische Ansicht des Befestigungselements 1 von unten. figure 1 is a schematic view of a fastening element 1 for connecting a first component 4 to a second component 6 and for compensating for tolerances between the first component 4 and the second component 6. figure 2 shows a schematic view of the fastening element 1 obliquely from below with a view of a lower drive interface 1.12. figure 3 shows a schematic sectional view of the fastener 1. figure 4 is a schematic view a section of the first component 4 with a receiving opening 4.1. figure 5 12 is a schematic view of the fastener 1 from below.

Das Befestigungselement 1 kann im Wesentlichen zylindrisch ausgebildet sein und weist eine Hülse 1.1 auf.The fastening element 1 can be essentially cylindrical and has a sleeve 1.1.

Das Befestigungselement 1 kann ein- oder mehrteilig ausgebildet sein und beispielsweise aus einem Metall- oder Kunststoffmaterial oder aus einer Kombination aus Metallteilen und Kunststoffteilen gebildet sein.The fastening element 1 can be designed in one or more parts and can be formed, for example, from a metal or plastic material or from a combination of metal parts and plastic parts.

Ein weiterer Aspekt sieht vor, dass die Hülse 1.1 einen Kopfabschnitt 1.3 aufweist, der als ein Dichtungselement ausgebildet sein kann, beispielsweise in Form einer Scheibe oder eines Pilzkopfes, und einen größeren Durchmesser als die Hülse 1.1 aufweist. Alternativ kann der Kopfabschnitt 1.3 auch lediglich mindestens zwei Sektoren, beispielsweise drei Sektoren, eines Pilzkopfes umfassen. Die Hülse 1.1 bildet eine Buchse des Befestigungselements 1. Die Hülse 1.1 und der Kopfabschnitt 1.3 können als ein Bauteil, insbesondere aus Kunststoff, gebildet sein. Beispielsweise sind die Hülse 1.1 und der Kopfabschnitt 1.3 als ein 2-Komponenten-Kunststoffspritzgussteil ausgebildet. Dabei kann die Hülse 1.1 aus einem härteren Kunststoffmaterial und der Kopfabschnitt 1.3 aus einem weicheren Kunststoffmaterial gebildet.A further aspect provides that the sleeve 1.1 has a head section 1.3, which can be designed as a sealing element, for example in the form of a disk or a mushroom head, and has a larger diameter than the sleeve 1.1. Alternatively, the head section 1.3 can also include only at least two sectors, for example three sectors, of a mushroom head. The sleeve 1.1 forms a socket of the fastening element 1. The sleeve 1.1 and the head section 1.3 can be formed as one component, in particular made of plastic. For example, the sleeve 1.1 and the head section 1.3 are designed as a 2-component plastic injection molded part. The sleeve 1.1 can be made of a harder plastic material and the head section 1.3 can be made of a softer plastic material.

In der Hülse 1.1 kann ein Ausgleichselement 1.4 verstellbar, insbesondere verstellbar in einer axialen Richtung y der Hülse 1.1, angeordnet sein. Die Hülse 1.1 und das Ausgleichselement 1.4 können hierfür mit zueinander komplementären Gewinden 1.8, 1.9 versehen sein.A compensating element 1.4 can be arranged in the sleeve 1.1 in an adjustable manner, in particular adjustable in an axial direction y of the sleeve 1.1. For this purpose, the sleeve 1.1 and the compensating element 1.4 can be provided with mutually complementary threads 1.8, 1.9.

Das Ausgleichselement 1.4 ist mit einer Aufnahme 1.2 versehen, insbesondere einer Hohlzylinderform.The compensating element 1.4 is provided with a receptacle 1.2, in particular in the form of a hollow cylinder.

In der Aufnahme 1.2 kann ein Federelement 2 angeordnet sein, beispielsweise aus Metall, insbesondere aus einem Stahlmaterial, vorzugsweise Federstahl.A spring element 2 can be arranged in the receptacle 1.2, for example made of metal, in particular of a steel material, preferably spring steel.

Das erste Bauteil 4 ist beispielsweise ein Trägerbauteil, insbesondere ein Karosserieblech eines Fahrzeugs. Die Aufnahmeöffnung 4.1 kann einen von der Kreisform abweichenden Querschnitt aufweisen. Die Hülse 1.1 kann eine zur Aufnahmeöffnung 4.1 komplementäre Schnittstelle 1.5 aufweisen. Ebenso kann die Aufnahmeöffnung 4.1 größer gestaltet sein als die Schnittstelle 1.5, um einen Positionsausgleich in Querrichtungen x und z quer zur axialen Richtung y der Hülse 1.1 zu ermöglichen.The first component 4 is, for example, a carrier component, in particular a body panel of a vehicle. The receiving opening 4.1 can have a cross section that deviates from the circular shape. The sleeve 1.1 can have an interface 1.5 that is complementary to the receiving opening 4.1. Likewise, the receiving opening 4.1 can be made larger than the interface 1.5 in order to allow a position compensation in transverse directions x and z transverse to the axial direction y of the sleeve 1.1.

Insbesondere können die Aufnahmeöffnung 4.1 und die Schnittstelle 1.5 jeweils einen annähernd quadratischen Querschnitt, vorzugsweise mit abgerundeten Ecken, aufweisen.In particular, the receiving opening 4.1 and the interface 1.5 can each have an approximately square cross section, preferably with rounded corners.

Die Aufnahme 1.2 im Ausgleichselement 1.4 ist zumindest einseitig, insbesondere kopfseitig, offen zur Aufnahme eines Verbindungselements 5 ausgebildet. Insbesondere kann die Aufnahme 1.2 als eine Durchgangsöffnung auch am bodenseitigen Ende und somit beidseitig offen ausgebildet sein.The receptacle 1.2 in the compensating element 1.4 is open on at least one side, in particular on the head side, to accommodate a connecting element 5. In particular, the receptacle 1.2 can also be designed as a through-opening at the bottom end and thus be open on both sides.

Ein zweites Bauteil 6, zum Beispiel ein Anbauteil, wie eine Heckleuchte oder eine Seitenleuchte, kann axial einstellbar an dem ersten Bauteil 4, zum Beispiel einem Trägerbauteil, wie einem Karosserieblech, befestigt oder befestigbar sein.A second component 6, for example an add-on part such as a rear light or a side light, can be attached or attachable to the first component 4, for example a carrier component such as a body panel, in an axially adjustable manner.

Das Befestigungselement 1 kann an dem ersten Bauteil 4, beispielsweise fahrzeugseitig, vormontiert werden. Beispielsweise kann das Befestigungselement 1 mittels einer Rast- oder Klemmverbindung in einer Aufnahmeöffnung 4.1 des ersten Bauteils 4 angeordnet und dort form- und/oder kraftschlüssig gehalten werden. In der gezeigten Ausführungsform ist eineThe fastening element 1 can be preassembled on the first component 4, for example on the vehicle side. For example, the fastening element 1 can be arranged in a receiving opening 4.1 of the first component 4 by means of a latching or clamping connection and can be held there in a positive and/or non-positive manner. In the embodiment shown, one

Mutter 1.6 vorgesehen, die auf die Hülse 1.1 aufgeschraubt werden kann, um das Befestigungselement 1 am ersten Bauteil 4 mittels einer Schraubverbindung zu halten. Hierzu können in der Mutter 1.6 und auf der Hülse 1.1 weitere komplementäre Gewinde 1.10, 1.11 vorgesehen sein. Weiter kann die Mutter 1.6 einen Bund 1.7 zur Anlage am ersten Bauteil 4 aufweisen.Nut 1.6 is provided, which can be screwed onto the sleeve 1.1 in order to hold the fastening element 1 on the first component 4 by means of a screw connection. For this purpose, further complementary threads 1.10, 1.11 can be provided in the nut 1.6 and on the sleeve 1.1. Furthermore, the nut 1.6 can have a collar 1.7 for resting on the first component 4.

Ebenso kann das Verbindungselement 5 an dem zweiten Bauteil 6, beispielsweise anbauseitig an der Heckleuchte oder Seitenleuchte, vormontiert werden. Beispielsweise weist das Verbindungselement 5 einen Gewindeabschnitt 5.1 auf. Der Gewindeabschnitt 5.1 kann als ein selbstfurchendes oder metrisches Gewinde, insbesondere selbsthemmend, ausgebildet sein, welches in einer Aufnahme des zweiten Bauteils 6 form- und/oder kraftschlüssig eingreift, insbesondere einschraubt. Alternativ kann das Verbindungselement 5 in dem zweiten Bauteil 6 festgelegt, beispielsweise eingepresst, eingeklebt, eingespritzt oder eingeclipst sein.Likewise, the connecting element 5 can be preassembled on the second component 6, for example on the mounting side on the rear light or side light. For example, the connecting element 5 has a threaded section 5.1. Threaded section 5.1 can be designed as a self-tapping or metric thread, in particular self-locking, which engages, in particular screws, in a receptacle of second component 6 in a positive and/or non-positive manner. Alternatively, the connecting element 5 can be fixed in the second component 6, for example pressed in, glued in, injected or clipped in.

Anschließend wird das Verbindungselement 5 mit dem vormontierten zweiten Bauteil 6 an dem ersten Bauteil 4 befestigt, wobei die Verbindung beider Bauteile 4 und 6 axial einstellbar ist.The connecting element 5 is then fastened to the first component 4 with the preassembled second component 6, the connection of the two components 4 and 6 being axially adjustable.

Das Verbindungselement 5 ist als ein Bolzen ausgeführt, der zur Abtrennung eines ersten Befestigungsbereiches 5.4 für die Aufnahme 1.2 im Ausgleichselement 1.4 von einem zweiten Befestigungsbereich 5.5 für das zweite Bauteil 6 einen Trennflansch 5.6 aufweist. Der Trennflansch 5.6 steht radial nach außen vor und ist scheibenförmig in Art eines Bolzenbundes ausgeführt und kann mit einem Sechskant oder Vierkant versehen sein.The connecting element 5 is designed as a bolt which has a separating flange 5.6 for separating a first fastening area 5.4 for the receptacle 1.2 in the compensating element 1.4 from a second fastening area 5.5 for the second component 6. The separating flange 5.6 protrudes radially outwards and is disk-shaped in the manner of a bolt collar and can be provided with a hexagon or square.

In einer Ausführungsform ist am Ausgleichselement 1.4 eine untere Antriebsschnittstelle 1.12 vorgesehen, beispielsweise ein Außen- oder Innensechskant oder -vierkant, ein Außen- oder Innensechsrund, ein Schlitz oder ein Kreuzschlitz. Die untere Antriebsschnittstelle 1.12 weist insbesondere vom in das Ausgleichselement 1.4 eingesetzten Verbindungselement 5 weg und kann aus der Hülse 1.1 herausragen, wenn das Ausgleichselement 1.4 in der Hülse 1.1 angeordnet ist.In one embodiment, a lower drive interface 1.12 is provided on the compensating element 1.4, for example an external or internal hexagon or square, an external or internal hexalobe, a slot or a Phillips slot. The lower drive interface 1.12 points in particular away from the connecting element 5 used in the compensating element 1.4 and can of the sleeve 1.1 protrude when the compensating element 1.4 is arranged in the sleeve 1.1.

In einer Ausführungsform ist alternativ oder zusätzlich am Ausgleichselement 1.4 eine obere Antriebsschnittstelle 1.13 vorgesehen, beispielsweise ein Außen- oder Innensechskant oder -vierkant, ein Außen- oder Innensechsrund, ein Schlitz oder ein Kreuzschlitz. Die obere Antriebsschnittstelle 1.13 weist insbesondere zu dem in das Ausgleichselement 1.4 eingesetzten Verbindungselement 5 hin und ist insbesondere dann zugänglich, wenn das Verbindungselement 5 nicht in das Ausgleichselement 1.4 eingesetzt ist.In one embodiment, an upper drive interface 1.13 is provided as an alternative or in addition to the compensating element 1.4, for example an external or internal hexagon or square, an external or internal hexalobe, a slot or a Phillips slot. The upper drive interface 1.13 points in particular to the connecting element 5 inserted into the compensating element 1.4 and is accessible in particular when the connecting element 5 is not inserted into the compensating element 1.4.

Die Mutter 1.6 und das Ausgleichselement 1.4 können eine zueinander komplementäre Verzahnung 1.14, 1.15 aufweisen, die das Lösen oder Verlieren der Mutter 1.6 erschwert oder verhindert.The nut 1.6 and the compensating element 1.4 can have mutually complementary toothing 1.14, 1.15, which makes it difficult or impossible to loosen or lose the nut 1.6.

Durch Befestigen des Gewindeabschnitts 5.1 in der Aufnahme des zweiten Bauteils 6, beispielsweise durch Einschrauben, kann eine Baugruppe gebildet werden, wie in Figur 6 gezeigt. Der Gewindeabschnitt 5.1 kann beispielsweise bis zum Anschlagen des Trennflansches 5.6 am zweiten Bauteil 6 eingeschraubt werden.An assembly can be formed by fastening the threaded section 5.1 in the receptacle of the second component 6, for example by screwing it in, as in FIG figure 6 shown. The threaded section 5.1 can, for example, be screwed in until the separating flange 5.6 hits the second component 6.

In einer Ausführungsform wird die Hülse 1.1 mit dem darin eingesetzten Ausgleichselement 1.4, wie in Figur 7 gezeigt, am Verbindungselement 5 befestigt, beispielsweise formschlüssig und/oder reibschlüssig. Diese Verbindung, beispielsweise über das Federelement 2, ist durch Herausziehen des Verbindungselements 5 aus der Aufnahme 1.2 wieder lösbar. Hierzu kann das Ausgleichselement 1.4 entsprechend elastisch ausgebildet sein.In one embodiment, the sleeve 1.1 with the compensating element 1.4 inserted therein, as in figure 7 shown attached to the connecting element 5, for example, positively and / or frictionally. This connection, for example via the spring element 2, can be released again by pulling the connecting element 5 out of the receptacle 1.2. For this purpose, the compensating element 1.4 can be designed to be correspondingly elastic.

Alternativ ist die Hülse 1.1 mit dem darin eingesetzten Ausgleichselement 1.4 vor der Montage der Komponenten 4, 6 bereits am Verbindungselement 5 befestigt, beispielsweise formschlüssig und/oder reibschlüssig.Alternatively, the sleeve 1.1 with the compensating element 1.4 inserted therein is already attached to the connecting element 5 before the assembly of the components 4, 6, for example in a form-fitting and/or friction-fitting manner.

Die Baugruppe, umfassend das zweite Bauteil 6 und das in der Aufnahme befestigte Befestigungselement 1, kann dem ersten Bauteil 4, beispielsweise einem Karosserieblech eines Fahrzeugs, zugeführt werden, wobei die Hülse 1.1 in die Aufnahmeöffnung 4.1 des ersten Bauteils 4 eingeführt werden kann, wie in Figur 8 gezeigt. Figur 8 ist eine schematische Ansicht des in das erste Bauteil 4 eingesetzten Befestigungselements 1 und des damit verbundenen zweiten Bauteils 6. In diesem Zustand kann ein Positionsausgleich in den Querrichtungen x und z quer zur axialen Richtung y der Hülse 1.1 erfolgen. Der Ausschnitt 4.1 kann ferner einen kleineren Durchmesser als der Kopfabschnitt 1.3 aufweisen.The assembly, comprising the second component 6 and the fastening element 1 fastened in the receptacle, can be fed to the first component 4, for example a body panel of a vehicle, with the sleeve 1.1 being able to be inserted into the receptacle opening 4.1 of the first component 4, as shown in FIG figure 8 shown. figure 8 is a schematic view of the fastening element 1 inserted into the first component 4 and the second component 6 connected thereto. In this state, a position compensation can take place in the transverse directions x and z transverse to the axial direction y of the sleeve 1.1. The section 4.1 can also have a smaller diameter than the head section 1.3.

Figur 9 ist eine schematische Ansicht des in das erste Bauteil 4 eingesetzten Befestigungselements 1 und des damit verbundenen zweiten Bauteils 6, wobei die Mutter 1.6 auf die Hülse 1.1 aufgeschraubt ist. Somit ist das Befestigungselement 1 am ersten Bauteil 4 befestigt und bezüglich der Querrichtungen x und z fixiert. figure 9 is a schematic view of the fastening element 1 inserted into the first component 4 and of the second component 6 connected thereto, with the nut 1.6 being screwed onto the sleeve 1.1. The fastening element 1 is thus fastened to the first component 4 and fixed with respect to the transverse directions x and z.

Nach der so erfolgten Montage des zweiten Bauteils 6 am ersten Bauteil 4 mittels des Befestigungselements 1 kann durch Verdrehen des Ausgleichselements 1.4 mittels der unteren Antriebsschnittstelle 1.12 eine axiale Position des zweiten Bauteils 6 relativ zum ersten Bauteil 4 eingestellt werden. Wird das zweite Bauteil 6 nun in axialer Richtung y abgezogen wie in Figur 10 gezeigt, dann verbleibt das bolzenförmige Verbindungselement 5 in der Aufnahme 6.1 des zweiten Bauteils 6 und die Hülse 1.1, das Ausgleichselement 1.4 und die Mutter 1.6 verbleiben in der Aufnahmeöffnung 4.1 des ersten Bauteils 4, beispielsweise einem Trägerbauteil, wie einem Karosserieblech. Figur 10 ist eine schematische Ansicht des Befestigungselements 1 nach dem Abziehen des zweiten Bauteils 6 vom ersten Bauteil 4.After the second component 6 has been mounted on the first component 4 using the fastening element 1, an axial position of the second component 6 relative to the first component 4 can be adjusted by rotating the compensating element 1.4 using the lower drive interface 1.12. If the second component 6 is now removed in the axial direction y as in figure 10 shown, then the bolt-shaped connecting element 5 remains in the receptacle 6.1 of the second component 6 and the sleeve 1.1, the compensating element 1.4 and the nut 1.6 remain in the receptacle opening 4.1 of the first component 4, for example a carrier component such as a body panel. figure 10 is a schematic view of the fastening element 1 after the second component 6 has been pulled off the first component 4.

In diesem Zustand ist auch die obere Antriebsschnittstelle 1.13 zugänglich, so dass das Ausgleichselement 1.4 auch auf diese Weise in axialer Richtung y verstellt werden kann.In this state, the upper drive interface 1.13 is also accessible, so that the compensating element 1.4 can also be adjusted in the axial direction y in this way.

In einer alternativen Ausführungsform können die Aufnahme 1.2 und das Verbindungselement 5 im ersten Befestigungsbereich 5.4 eine umlaufende Hohlkehle des Verbindungselements 5 und eine dazu komplementäre Ausbauchung der Aufnahme 1.2 umfassen.In an alternative embodiment, the receptacle 1.2 and the connecting element 5 in the first fastening area 5.4 can comprise a circumferential groove of the connecting element 5 and a bulge of the receptacle 1.2 complementary thereto.

In einer alternativen Ausführungsform kann das Verbindungselement 5 im ersten Befestigungsbereich 5.4 eine umlaufende Hohlkehle aufweisen und die Aufnahme 1.2 auf ihrer Innenseite dazu eine komplementäre Ausbauchung aufweisen, die in die Hohlkehle eingreift. Die Hohlkehle im Verbindungselement 5 kann zum Verbindungselement 5 in Richtung vom zweiten Bauteil 6 weg in einem steileren Winkel verlaufen als in entgegengesetzter Richtung, so dass das Verbindungselement 5 leichter in die Aufnahme 1.2 einführbar als daraus herausziehbar ist.In an alternative embodiment, the connecting element 5 can have a circumferential groove in the first fastening area 5.4 and the receptacle 1.2 can have a complementary bulge on its inside, which engages in the groove. The groove in the connecting element 5 can run at a steeper angle to the connecting element 5 in the direction away from the second component 6 than in the opposite direction, so that the connecting element 5 can be inserted more easily into the receptacle 1.2 than it can be pulled out.

In einer alternativen Ausführungsform kann das Verbindungselement 5 im ersten Befestigungsbereich 5.4 zylindrisch gebildet sein und die Aufnahme 1.2 auf ihrer Innenseite dazu komplementär ebenfalls zylindrisch gebildet sein.In an alternative embodiment, the connecting element 5 can be formed cylindrically in the first fastening area 5.4 and the receptacle 1.2 can also be formed cylindrically on its inside, complementary thereto.

In einer alternativen Ausführungsform kann das Verbindungselement 5 im ersten Befestigungsbereich 5.4 im Wesentlichen zylindrisch gebildet und mit einer Riffelung versehen sein und die Aufnahme 1.2 auf ihrer Innenseite ebenfalls im Wesentlichen zylindrisch gebildet sein. In der Aufnahme 1.2 ist ein Federelement 2 angeordnet und axial in beide Richtungen fest mit einer Innenseite der Aufnahme 1.2 verbunden.In an alternative embodiment, the connecting element 5 can be essentially cylindrical in the first fastening area 5.4 and provided with ribbing, and the receptacle 1.2 can also be essentially cylindrical on its inside. A spring element 2 is arranged in the receptacle 1.2 and is firmly connected axially in both directions to an inside of the receptacle 1.2.

Ein solches, axial in beide Richtungen innerhalb der Aufnahme 1.2 fixiertes Federelement 2 kann Kräfte, wie eine Einführkraft und eine Ausziehkraft, insbesondere Druck- bzw. Zugkräfte, axial in beide Richtungen übertragen und in Richtung der Aufnahme 1.2 ableiten, so dass das Befestigungselement 1 mehrmals genutzt werden kann.Such a spring element 2, which is fixed axially in both directions within the receptacle 1.2, can transmit forces, such as an insertion force and an extraction force, in particular compressive or tensile forces, axially in both directions and divert them in the direction of the receptacle 1.2, so that the fastening element 1 can be attached several times can be used.

In einer möglichen Ausführungsform sind die Hülse 1.1 aus Kunststoff und das Federelement 2 aus Metall gebildet.In a possible embodiment, the sleeve 1.1 is made of plastic and the spring element 2 is made of metal.

Das Federelement 2 umfasst beispielsweise einen Basiskörper, von welchem radial nach außen Federarme abstehen, die form- und/oder kraftschlüssig in die Innenseite der Aufnahme 1.2 eingreifen. Mittels der Federarme lassen sich gezielt axial wirkende Kräfte und deren Ableitung in beide Richtungen einstellen.The spring element 2 comprises, for example, a base body from which spring arms protrude radially outwards, which are positively and/or non-positively connected to the inside of recording 1.2 intervene. By means of the spring arms, axially acting forces and their derivation in both directions can be set in a targeted manner.

Der Basiskörper des Federelements 2 ist beispielsweise hülsenförmig ausgebildet. Die mehreren Federarme sind beispielsweise entlang einer Längsausdehnung des Basiskörpers übereinander in mehreren Reihen angeordnet oder ausgebildet. Dabei können die Federarme bezüglich des Basiskörpers einander diametral gegenüberliegend angeordnet oder ausgebildet sein. Eine solche, insbesondere zweiseitige oder zweireihige, Anordnung von Federarmen am Basiskörper ermöglicht eine symmetrische Kraftübertragung und -ableitung.The base body of the spring element 2 is, for example, sleeve-shaped. The multiple spring arms are arranged or formed one above the other in multiple rows, for example, along a longitudinal extent of the base body. The spring arms can be arranged or formed diametrically opposite one another with respect to the base body. Such an arrangement of spring arms on the base body, in particular on two sides or in two rows, enables symmetrical force transmission and dissipation.

Alternativ kann eine einseitige oder einreihige Anordnung von Federarmen am Basiskörper ausgebildet sein, welche eine asymmetrische Kraftübertragung und -ableitung ermöglicht.Alternatively, a one-sided or single-row arrangement of spring arms can be formed on the base body, which enables asymmetrical force transmission and dissipation.

Zusätzlich kann der Basiskörper außerhalb der Reihen der Federarme bereichsweise einen wellenförmigen Abschnitt aufweisen. Dieser wellenförmige Abschnitt des Basiskörpers ermöglicht einen Reib- oder Klemmschluss mit der Innenseite der Aufnahme 1.2 außerhalb des Form- und/oder Kraftschlusses der Federarme mit der Innenseite.In addition, the base body can have a wavy section in some areas outside of the rows of spring arms. This wave-shaped section of the base body enables a frictional or clamping connection with the inside of the receptacle 1.2 outside of the positive and/or non-positive connection of the spring arms with the inside.

Die Federarme können radial nach außen ab stehen und dringen dann im in der Aufnahme 1.2 eingesetzten Zustand in die Innenseite der Aufnahme 1.2 ein und bilden einen Form- und/oder Kraftschluss mit der Innenseite der Aufnahme 1.2.The spring arms can protrude radially outwards and then, when inserted in the receptacle 1.2, penetrate into the inside of the receptacle 1.2 and form a positive and/or non-positive fit with the inside of the receptacle 1.2.

Zusätzlich kann der Basiskörper Federarme aufweisen, die radial nach innen gerichtet sind und vom Basiskörper radial nach innen abstehen.In addition, the base body can have spring arms which are directed radially inwards and protrude radially inwards from the base body.

Beispielsweise weisen benachbarte Federarme und mindestens einer der Reihen abwechselnd radial nach außen und radial nach innen gerichtete Federenden auf. Darüber können die Federarme einer oder der jeweiligen Reihe in einem axialen Abstand zueinander angeordnet sein. Dies ermöglicht eine axiale Einstellbarkeit der Verbindung, beispielsweise mittels entsprechender Abstände in Verstellschritten. Hierdurch sind axiale Verstellschritte zum Ausgleich von Toleranzen, insbesondere von kleinen Bauteiltoleranzen, in kleinen Schritten von beispielsweise 0,2 cm bis 1 cm, insbesondere von 0,35 cm möglich.For example, adjacent spring arms and at least one of the rows alternately have spring ends pointing radially outwards and radially inwards. Above this, the spring arms of one or the respective row can be arranged at an axial distance from one another. This enables the connection to be adjusted axially, for example by means of appropriate spacing in adjustment steps. This enables axial adjustment steps to compensate for tolerances, in particular small component tolerances, in small steps of, for example, 0.2 cm to 1 cm, in particular 0.35 cm.

Dabei können die Federarme als Rastarme, Ratschen oder Klemmarme oder in einer anderen geeigneten Form ausgebildet sein, welche ein Form- und/oder Kraftschluss mit einer angrenzenden Fläche, wie der Innenseite der Aufnahme 1.2 ermöglicht.The spring arms can be designed as latching arms, ratchets or clamping arms or in another suitable form which enables a positive and/or non-positive fit with an adjacent surface, such as the inside of the receptacle 1.2.

Die Aufnahme 1.2 kann in allen Ausführungsformen im Bereich des Kopfabschnitts 1.3 trichterartig gebildet sein, um das Einführen des Verbindungselements 5 zu erleichtern.In all embodiments, the receptacle 1.2 can be formed like a funnel in the area of the head section 1.3 in order to facilitate the insertion of the connecting element 5.
